NAME
sysctl.conf - sysctl preload/configuration file
DESCRIPTION
sysctl.conf
is a simple file containing sysctl values to be read in and set by
sysctl.
The syntax is simply as follows:
-
# comment
; comment
token = value
Note that blank lines are ignored, and whitespace before and after a token or
value is ignored, although a value can contain whitespace within. Lines which
begin with a # or ; are considered comments and ignored.
If a line begins with a single -, any attempts to set the value that fail will be
ignored.
NOTES
As the
/etc/sysctl.conf
file is used to override default kernel parameter values, only a small number of parameters is predefined in the file.
Use
/sbin/sysctl -a
or follow
sysctl(8)
to list all possible parameters. The description of individual parameters can be found in the kernel documentation.
Maximum supported line length of the value is 4096 characters due
to a limitation of /proc entries in Linux kernel.
EXAMPLE
-
# sysctl.conf sample
#
kernel.domainname = example.com
; this one has a space which will be written to the sysctl!
kernel.modprobe = /sbin/mod probe
